How can i use printf in java to to print formatted output

Question

I'm trying to format my output with System.out.printf(); function in java .
the output format is like this :

In each line of output there should be two columns: The first column contains the String and is left justified using exactly characters. The second column contains the integer, expressed in exactly digits; if the original input has less than three digits, you must pad your output's leading digits with zeroes.
================================
java 100
cpp 065
python 050
================================

Use String's format to format strings the way "sprintf" does in C.

From that reference, adapting to your need:

Padding left with zeros:

String.format("|%03d|", 93); // prints: |093|

String of spefiied length (involves max and min)
```
String.format("|%-15.15s|", "Hello World"); |Hello World   |
```
You want left justified so "-N" instead of N for first value

Java 8's official format reference: https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#format-java.lang.String-java.lang.Object...-

And format string documentation: https://docs.oracle.com/javase/8/docs/api/java/util/Formatter.html#syntax
